Except when it isn't obvious. What constitutes mutation of an object? C++ handles this with 'const', and lets the programmer cheat by using transient member variables, since there are cases when you actually want to mutate objects a little, but claim that you don't... Perhaps we need a.reverse? for just-mutating-a-little reverse as well? ;^) -- http://mail.python.org/mailman/listinfo/python-list
